Abstract: There is provided a method for producing a self-supporting ceramic composite comprising (1) a ceramic matrix obtained by oxidation of an aluminum zinc alloy to form a polycrystalline oxidation reaction product of the metal (10) with an oxidant, and (2) one or more fillers (12) embedded by the matrix. The metal alloy (10) and permeable mass of filler (12) having at least one defined surface boundary (14) are oriented relative to each other so that formation of the oxidation reaction product will occur into said mass of filler (12) and in a direction towards said defined surface boundary (14). On heating the metal (10) to a first temperature above its melting point but below the melting point of said oxidation reaction product to form a body of molten parent metal, the molten metal reacts with said oxidant to form said oxidation reaction product which infiltrates said mass of filler (12) to said defined surface boundary (14). The resulting infiltrated mass is heated to a second temperature in order to remove or oxidize at least a substantial portion of any residual non-oxidized metallic constituents from or in said infiltrated mass without substantial formation of said oxidation reaction product beyond said defined surface boundary (14), thereby producing a self-supporting ceramic composite.
